For me, what did the trick to understand continuations, was the
following piece of code:

Object>>escaperDo: aBlock
   ^ aBlock value: [ :value | ^ value ]

If you try to fully understand what it does, how it can be used and
what its limitations are, then you will also understand continuations
to which the limitations I am talking about don't apply.

So it is more like a quiz ;-)
